<p>There are <code>n</code> oranges in the kitchen and you decided to eat some of these oranges every day as follows:</p>
|
|
|
|
<ul>
|
|
<li>Eat one orange.</li>
|
|
<li>If the number of remaining oranges <code>n</code> is divisible by <code>2</code> then you can eat <code>n / 2</code> oranges.</li>
|
|
<li>If the number of remaining oranges <code>n</code> is divisible by <code>3</code> then you can eat <code>2 * (n / 3)</code> oranges.</li>
|
|
</ul>
|
|
|
|
<p>You can only choose one of the actions per day.</p>
|
|
|
|
<p>Given the integer <code>n</code>, return <em>the minimum number of days to eat</em> <code>n</code> <em>oranges</em>.</p>
|

<p><strong class="example">Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> n = 10
|
|
<strong>Output:</strong> 4
|
|
<strong>Explanation:</strong> You have 10 oranges.
|
|
Day 1: Eat 1 orange, 10 - 1 = 9.
|
|
Day 2: Eat 6 oranges, 9 - 2*(9/3) = 9 - 6 = 3. (Since 9 is divisible by 3)
|
|
Day 3: Eat 2 oranges, 3 - 2*(3/3) = 3 - 2 = 1.
|
|
Day 4: Eat the last orange 1 - 1 = 0.
|
|
You need at least 4 days to eat the 10 oranges.
|

<p><strong class="example">Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> n = 6
|
|
<strong>Output:</strong> 3
|
|
<strong>Explanation:</strong> You have 6 oranges.
|
|
Day 1: Eat 3 oranges, 6 - 6/2 = 6 - 3 = 3. (Since 6 is divisible by 2).
|
|
Day 2: Eat 2 oranges, 3 - 2*(3/3) = 3 - 2 = 1. (Since 3 is divisible by 3)
|
|
Day 3: Eat the last orange 1 - 1 = 0.
|
|
You need at least 3 days to eat the 6 oranges.
